T'ION OF NEW JERSEY 011" PATERSON, NEW JERSEY, a conrom- TEXTILE ROLL Application filed December 29,1980. SeriaLNo. 505,214.

This invention has for its object to improve rolls or roll-like bodies whose peripheral sur faces are adapted to grip fibrous textile material, such as the so-called sand-roller of the take-up mechanism of a loom. Such bodies are usually formed by providing a core and securing to its peripheral surface, as by glue or other cement, a covering of sand-paper; This construction is objectionable for several reasons. Thus the covering itself works loose or ives way in time; its gripping ac tion gradually becomes more and more m- .efi'ective, largely because the said particles be come detached; and, which is of more serious consequence, the faceted and consequently sharp angular form of the sand particles is known frequently to cut and badly damage 'the material gripped by the covering, par v ticularly, as in a loom, when the weaver manipulates the fabric as an incident to the oporation known as .picking back. By our invention we avoid all these objections as will appear from the following description, taken with the accompanying drawings, in which Fig. 1 shows a loom sand roller constructed according to the invention;

Fig. 2 is a fragmentary section thereof; Fig. 3 shows a fragmentary section thereof on a larger scale. a certain nodular formation being magnified above the actual size usually employed; and

Fig. 4; shows a fragmentary section of a modification of the invention.

Our invention is characterized by the roll or roll-like body having its periphery formed of metal and with numerous minute integral nodules which grip the fabric or other fibrous textile material placed in contact with, as extending more or lessaround, said peri hery. These nodules are to be distingui ed from particles such as compose the surface of v the usual sand-roller employed in loom takeup mechanisms in that, being more or less rounded protuberances and substantially wanting in sharp angles or corners such as characterize the faceted particles of sand, while they are found in practice to grip the fabric or equivalent material quite as tenaciously as sand particles, they will not cut or otherwise injure the material. They also continued to build u the core to be of a material different from that of the coating) our invention is further characterized by the coating directly adhering to the core instead of being in indirect adhering relation thereto, as in the case of sand-paper secured to the core of an ordinary sand-roller through the intermediary of a cementin substance.

How t e roll-like body is provided with the nodulated surfaceis not material, but we prefer to form the body as follows:

Having a suitable core 1 (which may be wood) by a blast we discharge onto its eriphery a spray of' fused metal partic es. The part cles, since they arrive at the surface in fused or molten state, adhere thereto directly, and of course as this procedure is a metal coating 3 they become welded toget er to form an integral mass. When the coating has been developed to any desired thicknesswhich, for a' body to take the place of the ordinary sand-roller, need not exceed the thickness of its sand-paper coating-the application of the metal particles is stopped, and the particles of the coating which are at its exterior surface will then beleft set or hardened as the mentioned nodules, 4, thereon,

The durability of the surface so far'as its gripping quality is concerned depends of course on the hardness of the metal of which the nodules are composed. On the other hand, we find that whilecertain hard metals can be fused and blasted in the form of fused particles in some cases good adhesion between the coating and the core is most certainly obtained if a soft metal priming layer-is first deposited on the core and then on this layer a hard metal or superficial layer having the nodules is deposited. This is shown by Fig.

4, 'where 5 indicates the riming layer and 6 the nodulated superficia layer.

Nodules as 7 in Fig. 3 are in fact formed at the inner periphery of the metal coatin inset in the core where the same is of woo or other material which the molten metal particles by their heat will burn or fuse. An other feature of our invention, therefore, involves this inset condition of such nodules taken with the forming of the coatinghso that it surrounds and closely embraces t e core, and this feature is independent of the form of the exterior or gripping surface of the-- coating, some way or not. A bond in such case results which insures against slippage of the coating on the core as a possible incident of expansion of the former or contraction of the latter.

Having thus fully described our invention what we claim is 1. A roll-like body having its periphery adapted to grip textile fibrous material and formed of metal and with numerous minute integral gripping nodules.

2. A roll-like body adapted at its periphery to grip fibrous textile material and comprising a core and a coating of metal extendingi around and directly adhering to the core an formed at its outer periphery with numerous 'minute integral gripping nodules.

3. A roll-like body adapted at its periphery to grip fibrous textile material and comprising a core and a coating of metal surroundmg and closely embracing the core and having its inner periphery formed with nodules inset in the core? In testimony whereof we aflix our signatures.
